1. `foo?.3:.5` should be unambiguously `foo ? 0.3 : 0.5`, because `3` is a number, not an identifier. `foo?.3` in any other context should be a syntax error. It's also inconsistent with array access otherwise. 2. I wouldn't have a problem with `object?.[prop]`, since that's only one character more. It's still a lot easier.
